If you could turn the spent grounds into pellets, they could at least function in equipment designed to burn pelletized material. You might have to tinker with either the formulation of a binding agent that perhaps oxidizes the pellet in combustion, or is an accelerant, or perhaps with the airflow on the stove, but the spent grounds would at least be in a convenient format to handle and combust with conventional equipment.
You ought to ventilate your mind and let the cobwebs out of it. Use this cup to catch the tiny ads:
